When "Dexter's" eighth season premieres June 30, Deb and her brother clearly have mixed feelings about Capt. Maria LaGuerta's demise.

"A better person would feel bad about LaGuerta's death, but the truth is it solved all my problems," voices the serial killer, played by Michael C. hall, in a new Showtime promo for both "Dexter" and "Ray Donovan," the new drama starring Liev Schreiber.

But Miami Metro Homicide's volatile lieutenant, Debra Morgan (Jennifer Carpenter), bitterly regrets firing on her captain in the season seven finale. In fact, she wishes she'd pulled the trigger on her adopted brother instead.
